Well, I think you have got one tiny chance to win people back. And that is to show a working prototype beforehand. That would be great if this could happen at E3 as you plan. Of course people are going to scrutinse that prototype , so make sure it's the real deal and not another Coleco Chameleon situation
Also, you say you are willing to listen to people. Here's some suggestions that I feel you absolutely need to do.
1) Get rid of the bottom screen, now that the top screen covers a lot of the bottom screen when open, it's pointless having it. Plus it was meaningless to start with. I don't think anyone would use it for anything.
2) Get rid of the second Mediatek SOC. The Z8750 is going to be a hungry enough SOC for battery life, having two SOCs working will just be a nightmare. And lets not forget the huge cooling issue you are going to have with two SOCs
